Port config problem with WiModem

[antipas]

I am trying to run a BBS on my C64 using the WiModem. I am able to access other BBS systems through my C64 but cannot connect to my BBS from an external computer.

I forwarded the internal and external ports in my router to 6400 and 1541 but neither ports are detected as open when I test them with a port checking tool.

Executing the ATI command does show that the incoming port is set to 6400 and the outgoing port is 1541. My router asks for an internal and external port in the forwarding settings which are directed to the WiModem.

Any help would be appreciated.

Thanks
